متن کاملDietary Omega-3 Fatty Acids and Improvement of Visual Acuity in School -Age Children
Previous studies have supported the benefit of increased intakes of DHA (docosahexaenoic acid) omega-3 fatty acid during pregnancy and lactation (or via infant formula) on visual acuity in infants and young toddlers. The present study was directed to investigate the potential benefit of enhanced dietary omega-3 fatty acid intakes in children ages 7-12 on visual acuity. The study population comp...
